I gave the user a debugging patch, but they reported that they
can no longer trigger the issue with 2.6.31.1

See:

	http://marc.info/?l=linux-ide&m=125469615425454&w=4

Maybe that's enough to close this, I dunno.

I'm the user with the debugging patch, I'd say no, don't close it.

Even though on my first tests I had the computer to crash the two weekends I
had tested, it seems that crashing on weekend was only luck and seems that
having the bug appear is more difficult than I had thought.

So... my comments saying that 2.6.31.1 seemed ok are probably wrong (I have
read the .1 changelog and there is an ata patch, but probably unrelated). It
is true that I had 2.6.31.1 running for a whole week without it crashing,
but seems that crashing it may need more time.

I'm now back to the 2.6.31 with the patch to debug it (3 days uptime) in
order to gather more info and after I get the info from 2.6.31 I'd test
3.6.31.latest or even 2.6.32whatever in case you find that better.

Regards...

Hi!

Sorry for not answering before, I've been running 2.6.31 patched for all
this time and the results are a bit dissapointing...

The first run was for almost a month and ended up with half a hang, I could
read on the console that there had been an error on one of the disks, dma
error, the keyboard was working, getty seemed to work but then login didn't
show up when entering the username even though the disks led was flashing
when I operated the console entering usernames and all that. This hang was
not like the hangs I had before, don't know if it was due to the patch and
the unknown operation arriving to the IDE disk, but the message that the
patch was supposed to display was not displayed at all.

The second run is current run I believe, currently it has an uptime of 18
days and not problem was showed over this time.

So... I'm afraid I'm not able to reproduce this and maybe the whole problem
is hardware related, even though the machine had been running with 2.6.30 in
a stable way, it is an old machine, so maybe it is not as healthy as I
believed, and even though memtest doesn't show any errors there could be
some dma problems or other weird things happening around :-(

So... I'd say you can close the bug and if I happen to find it again... I'll
report it again.

Sorry for all the noise.

Regards...
